Understanding medical diagnosis codes is crucial in healthcare, especially for accurate billing and record-keeping. In the realm of gynecology, the ICD-10-CM code N84.1 plays a significant role. This code specifically designates Polyp of cervix uteri, a condition that many women may encounter.
N84.1 is recognized as a billable/specific code within the ICD-10-CM system. This means it’s precise enough to be used for reimbursement purposes when diagnosing a cervical polyp in female patients. The code’s latest iteration, the 2025 edition of ICD-10-CM N84.1, became effective on October 1, 2024. It’s important to note that this is the American ICD-10-CM version, and international versions of ICD-10 N84.1 might have variations.
Within the ICD-10-CM coding rules, N84.1 is exclusively applicable to female patients. It specifically refers to a Mucous polyp of cervix. This clarifies that the code is intended for polyps originating from the cervix and characterized by their mucous nature.
While N84.1 is a specific code, it’s helpful to understand related terms. Approximate synonyms for N84.1 include:
- Adenomatous polyp of cervix
- Cervical polyp in pregnancy
- Endocervical polyp
- Polyp of cervix
- Polyp of cervix affecting pregnancy
- Polyp uterine cervix, adenomatous
These synonyms highlight the different ways a cervical polyp might be described, whether based on its tissue type (adenomatous), location (endocervical), or association with pregnancy. Regardless of the descriptive term used, the diagnosis often converges to the ICD-10-CM code N84.1 for coding and classification.
Looking at the code’s history, N84.1 is not a recent addition. It was established in 2016 (effective October 1, 2015) as a new code in the initial non-draft ICD-10-CM. Since then, through 2025, the code has remained unchanged, indicating its consistent application in medical coding.
To provide context within the broader ICD-10-CM code framework, here are some adjacent codes:
- N84.0 – Polyp of corpus uteri (Polyp of the body of the uterus)
- N84.2 – Polyp of vagina
- N84.3 – Polyp of vulva
- N84.8 – Polyp of other parts of female genital tract
- N84.9 – Polyp of female genital tract, unspecified
These adjacent codes illustrate that N84.1 is part of a larger category N84 – Polyp of female genital tract, which encompasses polyps in various locations within the female reproductive system.
In conclusion, N84.1 is the designated Cervical Polyp Diagnosis Code within the ICD-10-CM system. It’s a billable and specific code applicable to female patients, used for mucous polyps of the cervix. Understanding this code and its related terms is essential for healthcare professionals involved in diagnosis, treatment, and medical billing related to cervical polyps.
